Smart software <em>could</em> compensate by maintaining it&rsquo;s own century counter in the RTC&rsquo;s SRAM. However i doubt this device could last more than 200 years in the field.

I&rsquo;ve two DS3234 connected to two different Arduinos, I followed this tutorial http://www.l8ter.com/?p=375 one of them works perfectly but the other show me the following in Serial monitor:</p>

<p>It seems that every second increase all records in one unit, if I only read every 5 seconds they increased 5 units.
Could it be a wiring or soldering problem or is the DS3234 damaged?</p>
<p>Best regards.</p>Customer #451246 on COM-10079 - Real Time Clock - DS3234Customer #451246urn:uuid:c1e52dc4-08a7-2c82-dc05-2e47862689652013-07-02T10:23:09-06:00<p>I wish I could find an inexpensive WWVB receiver circuit to go along with this to set the time automatically (radio conditions permitting, of course). Sparkfun no longer offers their WRL-10060 RoH kit and the closest thing I found was from Galleon, which sells a receiver circuit (EM2s) @ $40 and an antenna $27 plus $20 s/h.</p>
<p>It&rsquo;s cheaper to cannibalize an &ldquo;atomic&rdquo; clock.</p>RobertC. on COM-10079 - Real Time Clock - DS3234RobertC.urn:uuid:e69a13bc-0987-765c-64dd-6d24f9c751eb2011-07-07T09:49:55-06:00<p>It should be in the SFE library.

We&rsquo;ve been waiting a LONG time for a board for this chip. It looks like such a great set of features for a good price. I wonder why it seems to have been orphaned by SparkFun?<br/>
While I wait for SF, it looks like I can get a 20 Pin SOIC adapter for 70 cents from Futurlec. I&rsquo;ll have to kludge the battery, etc. but really need to get on with the project.</p>mbrown9412 on COM-10079 - Real Time Clock - DS3234mbrown9412urn:uuid:a9524df2-e951-3ed3-c038-a9817afa90af2011-02-07T09:09:03-07:00<p>any due date on the board?</p>orcinus on COM-10079 - Real Time Clock - DS3234orcinusurn:uuid:6cca853a-dc71-7f6d-298d-2a1bb2e7bf362011-01-14T00:14:42-07:00<p>Two wires less?

Now if only sparkfun would do I2C. A current mirror &ldquo;breakout&rdquo; would solve many bus problems.</p>jbaruffa on COM-10079 - Real Time Clock - DS3234jbaruffaurn:uuid:8bf50f45-bc5c-1e2c-0440-d1a3eb5e2c382010-09-01T12:35:46-06:00<p>Vaild up to 2099? Is this the beginning of a Y2.1K bug?</p>
